n my opinion, The "SoLoMo" tourists are fit to Chiang Rai city because Chiang Rai has various attractions such as Natural Attractions, Historical and cultural attractions and other. Restaurants have cultural Identity, people have friendly, accommodations easily to find and low cost of living. Nowadays, people use telephone as more smart phones and the advancement of mobile technology in the present can do more than call into the call or receive short messages but smart phones can find a place to eat, drink, and travel or even reservation hotel via application for save time. Popular Apps are Foursquare, Wongnai, Groupon and Yelp. Nutchada Kingkaew 5431205076
